Apparatus for applying an adhesive substance to a fabric strip

Description

BACKGROUND OF THE INVENTION

[0001] The present invention relates to an apparatus for applying an adhesive substance to a fabric strip.

[0002] In order to stabilize the edge of a fabric piece to be used for making cloth articles of manufacture, to prevent the fabric from ragging or being damaged at the edge thereof, a lot of different systems, such as an application of an adhesive strip, are conventionally used.

[0003] Such a stabilizing system has been found as greatly advantageous, since it allows the fabric edge to be properly finished, without using seams or the like.

[0004] Moreover, the application of an adhesive strip allows to perform the fabric finishing operation without altering the resilient characteristics of the fabric and auxiliary materials.

[0005] The document JP-A-060 917 767 discloses a laminating apparatus for heat transferring a film to a surface to be protected.
The document US-A-5 851 342 discloses an apparatus and method for bonding a mulitple layer laminate by an adhesive to be arranged therebetween.

SUMMARY OF THE INVENTION

[0006] Accordingly, the aim of the present invention is to provide an apparatus for making adhesive strips of any desired types.

[0007] Within the scope of the above mentioned aim, a main object of the invention is to provide such an apparatus which is adapted to transfer either one or two adhesive strips from a paper support to a textile support, at either one or the other or both faces thereof.

[0008] Another object of the present invention is to provide such an apparatus allowing to remove exclusively the paper support if the adhesive substance has been applied to the textile or fabric support at one of the faces thereof.

[0009] Yet another object of the present invention is to provide such an apparatus which is operatively very flexible, and which, in particular, can be applied to a lot of different types of automatic machines for processing and making cloth articles of manufacture.

[0010] According to one aspect of the present invention, the above mentioned aim and objects, as well as yet other objects, which will become more apparent hereinafter, are achieved by an apparatus according to claim 1.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] With reference to the number references of figure 1, the apparatus according to the invention, which has been generally indicated by the reference number 1, comprises a supporting framework 2, designed for supporting a bobbin 3 supporting a paper support 4 in turn supporting an adhesive substance, and a fabric or support 6 supporting bobbin 5.

[0013] The paper support 4 is supplied to a heating plate 7 including interexchageable transfer guides 8 arranged upstream of an adjustable-pressure transfer wheel 9 operating in abutment against a bottom wheel 10.

[0014] The fabric support 6 is operatively driven by two timed entraining or driving wheels 10 and 11.

[0015] More specifically, the wheel 11 operates against a small wheel 12 associated with a pressure lever 13 for adjusting the driving of the fabric support 6.

[0016] The paper support 4, in turn, is driven through the bottom wheel 10, operating against a cooperating bottom small wheel 14 associated with a pressure lever 15 for adjusting the paper entrainment or driving.

[0017] At said bottom wheel 10 a paper support drawing device is provided, the paper support being disposed of after having transferred the adhesive substances to the fabric support 6.

[0018] Said fabric support 6, after the application of the adhesive substance thereto, will enter a pulling or tension device 16, by passing through a swinging roller 17 for controlling the fabric material 6 loop.

[0019] The apparatus shown in figure 2 allows to transfer an adhesive substance coming from two discrete and independent paper supports.

[0020] With reference to figure 2, the apparatus 101 comprises a framework support 102, designed for supporting two bobbins, respectively indicated by the reference numbers 103 and 133, each for a paper supported adhesive substance, as respectively indicated by 104 and 144, and a fabric support 106 bobbin 105.

[0021] The first paper support 104 is fed to a first heating plate 107 including interexchangeable transfer guides 108 arranged upstream of a transfer wheel 109, with an adjustable pressure, operating in abutment against a bottom wheel 110.

[0022] The second paper support 144 is fed to a second heating plate 177, including interexchangeable transfer guides 188, arranged upstream of the adjustable pressure transfer wheel 109, operating in abutment against the bottom wheel 110.

[0023] The driving of the fabric support 106 is carried out by a driving wheel 111, operating in abutment against a small wheel 112 associated with a pressure lever 113 for adjusting the driving or displacement of the fabric support 106.

[0024] The driving of the paper supports 104 and 144 is performed through the bottom wheel 110, operating in abutment against a bottom small wheel 114 associated with a pressure lever 115 for adjusting the paper material entrainment.

[0025] At the bottom wheel 110 is provided a drawing or suction device for drawing the paper support 104 which is disposed of after having transferred the adhesive substance to the fabric support 106.

[0026] The second paper support 144 is disposed of through a second drawing device arranged at the transfer wheel 109.

[0027] More specifically, the fabric support 106, with the adhesive substance applied thereto, enter a pulling or tension device 116, by passing through a swinging roller 117 controlling the loop of the fabric support 106.

[0028] Figures 3-6 show possible operating diagram for applying the adhesive substance to the fabric support by the apparatus according to the invention.

[0029] More specifically figure 3 shows an application diagram, which can be carried out through the apparatus 1, in which an adhesive layer 20 is applied on a side of the fabric support 6.

[0030] Figure 4 shows a further application diagram to be performed by the apparatus 1, in which two adhesive substance layers 20 and 21, coming from the same paper supports 4, are applied on a side of the fabric support 6.

[0031] Figure 5 shows a further application diagram to be performed by the apparatus 101, in which two adhesive substance layers 20 and 22, each coming from a respective paper support 104 and 144, are applied on two faces or sides of the fabric support 106.

[0032] Figure 6 shows yet another application diagram to be performed by the apparatus 1, in which an adhesive substance layer 20 is arranged between a fabric support 206 and a paper support 204, said supports 206 and 204 forming together a composite support 246 coming from a single bobbin 235.

[0033] By the apparatus according to the present invention, the paper support 204 is removed while leaving exposed the adhesive substance layer 20 on the fabric support 206.

[0034] In this connection, it should be pointed out that the adhesive substance applied on an adhesive substance support paper, for example a support paper strip can form either one or more continuous layers or it can be applied according to a point by point pattern thereby providing a grid configuration.

[0035] It has been found that the invention fully achieves the intended aim and objects.

[0036] In fact, the invention has provided an apparatus adapted to supply a fabric support, including one or more heated adhesive layers, ready for use in a finishing machine for finishing a cloth article of manufacture.

[0037] Advantageously, the apparatus according to the invention operates in an electropneumatic manner, and allows to transfer either one or two adhesive substances from a paper support to a fabric support, on one or two sides of the latter, and moreover allows to remove only the paper support, if the adhesive substance has been already applied to the fabric support, on said one or two sides thereof.

[0038] The subject apparatus can comprise moreover a support arrangement for assembling it on a finishing machine for performing finishing operations on cloth articles of manufacture, and can use a built-in control panel.

[0039] Moreover, the subject apparatus provides the possibility of interexchanging transfer guides for transferring paper support strips having a width from 6 to 40 mm.

[0040] The heating means included in the apparatus can be programmed with a temperature storing capability.

[0041] In practicing the invention, the used materials, as well as the contingent size and shapes, can be any, depending on requirements and the status of the art.
